Applioatibn filed November 27, 1912. Serial Ho. 733,913.

To all whom it may concern Be it known that we, JAMES MCNEIL and ROBERTLIENHARD, Jr., citizens of the United States of America, residing atPittsburgh, in the county of Allegheny and State of Pennsylvania, haveinvented certain new and useful Improvements in Elastic Spring-Supports, of which the following is a specification, reference being badtherein to the accompanying drawing.

This invention relates to an elastic spring support especially designedas a shock absorber for vehicles.

The primary object of-our invention is to furnish a vehicle withsuspension springs that insure comfort, reduce the wear and tear upontires and engine and greatly facilitate the speed of a vehicle.

Another object of our invention is to provide a shock absorber that canbe easily fitted to a car having various types of springs and withoutmodification to exist ing frame work.

A further object of this invention is to provide an elastic springcoupling that is dust proof, positive in its action, capable ofwithstanding the great weight of a vehicle body, and highly efficientfbr insuring comfort while traveling on the roughest roads at thegreatest rate of speed.

With the above and other objects in view the invention resides in thenovel construc tion, combination and arrangement of parts to behereinafter specifically described and then claimed.

Reference will now be had to the drawing,

wherein Figure 1 is a perspective view of the shock absorber as appliedto a portion of a laminated or leaf spring, Fig. 2 is an enlargedvertical sectional View of the shock absorber, and Fig. 3is a crosssectional view of the same, showing .a line HII representing the sectionline of Fig. 2.

Further describing our invention in detail with reference to theaccompanying drawing, wherein likenumerals denote 'corresponding partsthroughout: 1 denotes a portion of the lower leaf or laminated spring ofa vehicle and extending through the barrel 2 of said spring is a boltDetachably mounted upon the ends of said bolt and retained thereon bynuts 4: or other fastening means are the longitudinally apertured Theads 5 ofsuspension rods 6.

7 denotes 'a'portion of the upper leaf or or other yieldable material.

laminated spring of a vehicle and extending nto the barrel 8 of saidspring are confront- 1ng stud bolts 9 carried by heads 10 slidablymounted upon the suspension rods 6.

11 denotes an oblong spacer plate slidably mounted upon the rods 6, saidplate having openings 12 for tubular bosses 13 carried by the heads 10.

14 denotes a liner arranged upon the plate 11 between the heads 10 andthe barrel S, this liner compensating for any inequalities between theplate 11 and the barrel 8, where-- by the barrel 8 will have a firmbearing rela tively to the plate 11. In some instances the liner can bedispensed with.

15 denotes nuts screwed upon the lower threaded ends 16 of the bosses13, said nuts supporting the spacer plate 11.

17 denotes an oblong support movably arranged upon the lower ends of thesuspension rods 6 and the top of said support has bosses 18 confrontingthe nuts 15. Encircling the bosses 18 and the nuts 15 are the endconvolutions of coiled compression springs 19.

2O denotes an oblong gasket arranged against the lower side of thesupport 17, said gasket being made of leather, rubber The gasket isretained in position by a face plate 21 held upon the rods 6 by nuts 22,cotter pins 2?) or other fastening means.

24 denotes an oval casing having the upper edges thereof connected tothe edges ofthe spacer plate 11, as at 25 and said casing incloses therods 6 and the springs 19 and has the inner walls thereof engaged bvflanged edges 26 of the gasket 20. The flanged edges of said gasketexclude dust,

dirt and other matter which would tend to impair or injfirethe springs19. Furthermore the gasket 20 operates upon the princivic of a pistonwithin the casing'24 and in connection with the latter retains lubricanttherein. The casing 24 is of suflicient size whereby the outer sidesthereof can have placed thereon a license member or an advertisement.

From the foregoing it Will be observed that the suspension rods 6 aresupported by the lower spring 1 and that the support 1'? is retainedupon the lower ends of said rods. When a weight or pressure is broughtto bear upon the upper spring '7, the heads 10 of the stud bolts tendto'shift downwardly upon the suspension rods and place the springs 19under compression, these springs cushioning a downward movement of theupper spring relatively to the lower spring, and as the springs areinclosed they are not susceptible to injury by stone bruise.

The weight or pressure brought to bear upon the upper spring 7 actsdirectly upon the spacer plate 11 or the liner '14 without any unduestress or strain upon the stud bolts 9. These bolts normally positionthe end of the upper spring 7 relatively to the suspension rods andliability of said bolts shifting is reduced to a minimum through themedium of the bosses 13 extending through the spacer plate 11, thisplate cooperating With the bolt 3 in properly supporting the suspensionrods.

The springs 19 are normally under tension and cannot become accidentallydies.

placed even though the shock absorber is constantly in use.

. It is thought that the operation and uti1- ity of the spring supportwill be apparent without further description and we would have itunderstood that our invention is susceptible to such changes, as in thesize, shape, use and elastic medium, as fall within the scope of theappended claims.

What we claim is z 1. In a shock absorber, a bolt adapted to beconnected to the rear end of the lower spring of a vehicle, suspensionrods mounted upon the ends of said bolt, oppositely disposed stud boltsadapted to be connected to the rear end of the upper spring of thevehicle and having their heads formed with vertical openings and bossesthrough which saidrods extend, a spacer plate mounted upon said bossesand against said heads, means engaging the bosses for supporting thespacer plate, a support at the lower ends of means interposed betweenfly 1 2. In a shock absorber, a pair -.of oppositely disposed stud boltsadapted to be secured to the rear end of the upper spring of a vehicleand having their heads provided with vertical openings and bosses,suspension means adapted to be connectedto 'the rear end of the lowerspring of a vehicle and extending through said openings and bosses, aspacer plate mounted upon said bosses and abutting against said heads,means mounted upon the bosses for securing said spacer plate inposition, and cushioning elements supported by said suspension means. i

3. In a shock absorber, a pair of oppositely disposed stud bolts adaptedto be con= nected to the rear end of the upper spring of a vehicle andhaving their heads provided with vertical openings and peripherallythreaded depending bosses, suspension means adapted to be connected tothe rear end of the lower spring of a vehicle and extending through saidheads and bosses, a spacer plate mounted upon said bosses, nuts engagingsaid bosses for maintaining the spacer plate in position, and cushioningelements carried by said suspension means and abutting against saidplate.

In testimony whereof we affix our sig'natures in the'presence of twowitnesses;
